DUMPlNG-CAR.

Specification of Letters Patent.

Patented Jan. 23, 1906.

Application tiled July 31,1905- Serial No. 272,002.

To a/ZZ whom, it may concern,.-

Be it known that we, RICHARD W.I ERIC- soN and JOHN V. ERICsoN, citizensvof the -United States, residing at Chicago, in the county of Cook andState of Illinois, have invented new and useful Improvements inDumping-Cars, of which the following is a speciiication.

This invention is an improved dumpingcar particularly adapted forrailway use and having means for dumping loads to either, the middle orthe sides. The bottom is made with opposite side sections, .which can betilted in or out to dump to the center or the sides, as will more fullyhereinafter appear.

In the accompanying drawings, Figure 1 is a side elevation of a carconstructed according to the invention. Fig. 2 is a verticalcross-section. Fig. 3 is an end elevation. Fig.- i is a plan. Fig. 5 isa detail showing a hinged or flexible connection between an endfloor-section and a transom. Fig. 6` is a detail and cross-section ofthe same parts. Fig. 7 is an end view illustrating modified means forraising or lowering the bottom doors.

The frame of the car has continuous Center sills 10 and short side sills11v at each end.

lThe side posts 12, or such of them as are located between the sidesills at the respective ends, extend below the bottom and support theouter ends ofthe transoms 13, which are supported at the middle by thecenter sills.

The bottoni sections or doors 3 are arranged on each side of the centersill and between the transverse sills 13, and these doors tilt in eitherdirection to dump the load either to the center or to the sides. Saiddoors are supported by chains 2, connected to longitudinal shafts 1,which extend lengthwise of the car, ,and are supported at one end inbearings at 1a in one of the cross-sills and extend at the other endbeyond the end frame of the car, where they have pinions 7, which meshwith Worms 6a on the cross-shaft 6, which is mounted in bearings on theend of the car. This shaft 6 has a crank 8, whereby it may be turned.-The crank 8 is hinged to the shaft at 8a, so that it may be turned inand dropped into a notch at 15 in a bracket 16, which is bolted to theend of the car and also serves to support the shaft 6. The doors 3 areconnected to the chains 2 at the middle, so that they will swing ineither direction with equal facility. The doors close at their inneredges against the side `flanges 10a at the top of the center sill, andat their outer edges they close under the side planks of the car. Tosupport the inner edges of the doors, hooks 17 are provided. These hooksare hinged to the center sill and are locked under the edges of thedoors by means of cam-arms 18, carried by a shaft 19, which extendslengthwise along the middle sill and has at the end a lever '20, wherebyit may be turned. This lever is engaged and held in either position by aswinging latch 21, which engages a notch in either side of the lever.When the lever is lswung in one direction, the cam-arnis 18 turn againstthe hooks 17 and swing the same out under the edge of the doors and areheld' in this position by a latch and lever. When the inner edges of thedoors are to be released to permit the center dump, the lever 20 isswung over to the other side, which turns the cam-arms 18 from behindthe hooks and allows the hooks to swing back and the doors to drop, asindicated in dotted lines'in Fig. 2.

To support and control the outer edges of the doors, shafts 4 areprovided, extending lengthwise along the side of the car and lsupportedby the'side posts. These shafts have notched arms 4a, which may be swungin or out-into or out of e1igagement-under the outer edges of the door.Each shaft has -a handle 5, whereby it may be turned, and 5a indicates apivot-clip secured to the side of the car and which may be turned tohbld the handle when it is turned in. To eiiect the side dump, the clip5L is turned up and the handle 5 pulled out. This rocks the shaft 4 andswings the arms 4 out from under the doors, thereby releasing the outeredges thereof and allowing the same to drop and dump the load to thesides.

It will be seen that by the Construction .shown either a center or aside dump may be effected.

The parts are not complicated and thc supporting and releasing devicesi'or the doors are capable of easy and quick operation.

In order that the car may be used either as a flat-bottom orhopper-bottom car, means are provided for raising or lowering the endsections of the ear-floor. To this end said I i3, so that the{loer-sections maybe lifted or be raised when desired.

.lowered It is conveniently raised by ay winding-drum 24 on the outsideofI the car, to which a crank may be applied. Connected to this drum isa rope 25, which passes over the pulley 26, set in a recess in the sideoi the ear, near the upper edgethereot, and is at tached at its otherend to the floor-section.AA By means of the drum the floor-section canThe Hoor-sections 22 are grooved on the under side, at 22',

so as to let the shafts 1 pass through there' under to the end of thecar.

To hold the iloorsections up inraised position, a cross-piece 27 isprovided. This fits between the sides of the car and may be held bybolts 28 at the end ot the car, as shown at the right-hand end of Fig.1, or it may be moved along and located under the upper end of thelicor-section, as indicated at the lett-hand end of the ear, as shown inFig. l. In thelatter position it supports the end of the floor: 22 invraised position. this cross-piece is a board 29, vghich when thecross-piece is at the end ot the car hangs 4down beside said end andwhen the crosspiece is advanced covers the openingr between thefloor-sections and the end of the car, as illustrated at the lett-handend oi the car, (shown in Fig. 1,) and also provides a plat'- lorin orfoot-piece for the trairnncn to stand upon.

Instead of the worm-gear for raising the doors above described thedevices shown in Fig. 7 may be used. This figure shows at one place alever 3i), mounted upon the end of the shaft l and provided with a pawl3l to engage a ratchet-wheel 32 on said shaft, or, as shown at anotherplace, the ratchet-wheel may have a block provided with a. set of holes33, into which a lever-bar may he inserted to turn the shalt, in whichcase a pawl 34 prevents bach slip.

`What we claim as new, and desire to secure by Letters Patent, is

l. A dumping-ear having doors in the bottom, a nf'iiuling-shal't andmeans to turn the saine, a cable connecting the shaft and the middle oi'the doors, to permit them to swing either way, and releasahle means tosupport the doors at opposite edges thereof.

i 3. A. dumping-car having a row of doors in the bottoni on each sideol. the middle, a winding-shaft extending across each row, chainsconnecting the shalt and the middle of the doors, and `means to releaseeither the outer or the .inner edge et the doors, toellect either centeror side dump.

4. A, dumping-car having a row ot doors in the bottom on each side oi" amiddle sill, a winding-shat`t extending lengthwise across Ieach row ofdoors and having connections with the doors at about the middle thereof,so that'they will swing either way, and means to hold either edge ot thedoors and to release the opposite' edge.

The combination with a row of swinging doors in the bottom ot' adumping-ear, of a rock-sh ait extending along the side of the ear andhaving projectingr rigidly therefrom a series of supporting-arms havingnotched ends engageahle under the doors when closed, and diseng'ageableYtherefrom to allow the doors to open. Y
